fix(legacy): now macro should use station timezone (#3143)

### Description

The `now{}` macro for criteria filtering used UTC rather than station
timezone leading to confusing results.

**This is a new feature**:

No

**I have updated the documentation to reflect these changes**:

Yes

### Testing Notes

**What I did:**

I named a track the current date and hour, and used the date macro to
try to select it. It failed, I then implemented this fix and saw that
the track was selected.

**How you can replicate my testing:**

See what I did.

 To create a smart block, click the **Smartblocks** button on the left sidebar, and select **New** from the toolbar. Like a playlist, smart blocks can have a title and description, which you can edit. This helps you find relevant smart blocks in searches.
 
 Fill out the smart block's **Name**, **Search Criteria**, and **Limit to** sections. The search criteria can be any one of LibreTime's metadata categories, such as **Title**, **Creator** or **Genre**. The modifier depends on whether the metadata in question contains letters or numbers. For example, **Title** has modifiers including _contains_ and _starts with_, whereas the modifiers for **BPM** include _is greater than_ and _is in the range_.
-To filter tracks using today's date information, use the `now{}` macro. Format characters are listed in the [php documentation](https://www.php.net/manual/en/datetime.format.php). For example, to filter to tracks with a **Title** that ends in `Instrumental Jan 2024` where `Jan 2024` is the current month and year, add a criteria for **Title** with a modifier of **ends with** and a value of `Instrumental now{M Y}`.

The macro uses the configured station timezone to resolve dates and times.
 
 If you have a large number of files which meet the criteria that you specify, you may wish to limit the duration of the smart block using the **Limit to** field, so that it fits within the show you have in mind. Select **hours**, **minutes** or **items** from the drop-down menu, and click the **Generate** button again, if it's a static smart block. Then click the **Save** button.
